分布式控制系统中PC机与多个智能控制器数据通信的实现

The Realization of Data Communication between Single PC and Multiple Intelligent Controllers in Distributed Control System

阐述了DB1000智能控制器的通信协议以及主从式通信的原理,采用Pcomm串行通信开发工具实现了分布式控制系统中单台PC机对多台智能控制器的串行通信控制。

The communication protocol of the DB1000 intelligent controller and the principle of master-slave communication are introduced. Pcomm, a serial communication development tool is used to control serial communication between a single PC and multiple intelligent controllers in a distributed control system.
